[0029] In the following, the exemplary solutions of the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present utility model. Unless otherwise defined, the technical terms or scientific terms used in the present utility model should have the ordinary meanings understood by those of ordinary skill in the relevant art.
[0030] As Figure 1 shown, the circular rubber pad simple cutting die of this embodiment includes a stamping head 10, a pushing block 20 and a spring 40. A sliding cavity 11 is provided in the center of the stamping head 10; the pushing block 20 is arranged in the sliding cavity 11 through a bolt 30, and the pushing block 20 can reciprocate linearly in the sliding cavity 11 along the axial direction of the bolt 30; the spring 40 is also located in the sliding cavity 11 and is sleeved on the bolt 30, and is arranged between the pushing block 20 and the bottom wall of the sliding cavity 11, and this spring 40 is used to support the pushing block 20.
[0031] It should be understood that during the production process of the rubber sheet, due to the influence of its own hardness or elasticity, the rubber sheet is prone to bending deformation, which further increases the subsequent processing difficulty. In actual production, the roundness of the circular rubber pad formed by stamping the rubber sheet with a curved surface will also decrease, affecting the production quality. Therefore, it is necessary to extrude the rubber sheet flat and then cut it into a circular rubber pad.
[0032] As Figure 1 and Figure 2 shown, the stamping head 10 is cylindrical, and one end of it is turned into a thinner connecting rod 13. The connecting rod 13 can be installed on the pressing head of an external press through a pin shaft, thereby realizing the connection between the cutting die and the press. Further, the connecting rod 13 is a rod-shaped structure with a diameter of 11.5 mm.
[0033] As Figure 1 and Figure 2As shown in the figure, a sliding cavity 11 is provided along the central axis at the other end of the stamping head 10, and an internal threaded hole 12 communicates with the bottom of the sliding cavity 11. Further, the outer diameter of the stamping head 10 is 29 mm, and the length is 100 mm (this length includes the entire stamping head 10 and the connecting rod 13); the sliding cavity 11 is also cylindrical, the inner diameter of the sliding cavity 11 is 21 mm, and the length is 50 mm; the inner diameter of the internal threaded hole 12 is 6 mm, and the length is 15 mm.
[0034] As Figure 1 and Figure 2 shown, a stamping knife 14 is formed by turning at the end of the stamping head 10 away from the connecting rod 13, and the stamping knife 14 is used for cutting circular rubber pads.
[0035] As Figure 1 and Figure 2 shown, the stamping angle of the stamping knife 14 is 15°. Optionally, the size of the stamping angle can be selected and adjusted according to the hardness and elasticity of the rubber plate to be processed to ensure that the stamping knife 14 can smoothly cut out circular rubber pads.
[0036] As Figure 1 shown, the pushing block 20 is cylindrical and is arranged in the sliding cavity 11. When in the initial state, a part of the pushing block 20 is located inside the sliding cavity 11, and the other part is located outside the sliding cavity 11.
[0037] Further, there is a clearance fit between the pushing block 20 and the sliding cavity 11, and the fit clearance between the two is 0.5 mm.
[0038] As Figure 1 - Figure 3 shown, a counterbore 21 is provided at the center of the pushing block 20, and the bolt 30 passes through the counterbore 21 and is screwed into the internal threaded hole 12. It should be understood that the head of the bolt 30 is located in the pushing block 20, and the screw of the bolt 30 passes through the counterbore 21 and the sliding cavity 11 and is screwed into the internal threaded hole 12. On the one hand, it can realize the linear sliding of the pushing block 20 along the screw of the bolt 30 and avoid the swinging of the pushing block 20; on the other hand, when the spring 40 pushes the pushing block 20 out of the sliding cavity 11, the pushing block 20 will not fall off the bolt 30.
[0039] Further, the diameter of the pushing block 20 is 20 mm, and the length is 22 mm.
[0040] Further, in this embodiment, the thickness of the used rubber pad is 4 mm.
[0041] As Figure 1 shown, a spring 40 is sleeved outside the bolt 30. One end of the spring 40 abuts against the bottom wall of the sliding cavity 11, and the other end abuts against the inner side wall of the pushing block 20. Further, the initial length of the spring 40 is 35 mm, and the diameter is 18 mm.
[0042] The working principle of this application is as follows:
[0043] Assembly of the simple cutting die for circular rubber pads:
[0044] S1. Place the spring 40 and the push block 20 into the sliding cavity 11 of the stamping head 10 in sequence.
[0045] S2. Pass the bolt 30 through the counterbore of the push block 20 and the spring 40 in sequence, and thread it into the internal thread hole 12.
[0046] S3. As shown in Figure 1 Turn the adjusting bolt 30 to adjust the connection depth in the internal thread hole 12 until a part of the push block 20 is exposed outside the sliding cavity 11 and the other part is located inside the sliding cavity 11.
[0047] So far, the assembly of the simple cutting die for circular rubber pads is completed, and the total length of the cutting die after assembly is 107 mm.
[0048] Cutting process of circular rubber pads:
[0049] S1. Place the rubber sheet on the plywood, fix it with thumbtacks or clamps, and put the rubber sheet and the plywood together on the pressing workbench of the press.
[0050] S2. Install the assembled cutting die on the pressing head of the press through the connecting rod 13.
[0051] S3. Start the press, and the cutting die descends following the pressing head of the press.
[0052] During this descent, the push block 20 first contacts the rubber sheet. Under the action of the elastic force of the spring 40, the (bent) rubber sheet is gradually squeezed by the push block 20 to a flat state; meanwhile, the spring 40 continuously contracts, and the push block 20 continuously slides into the sliding cavity 11.
[0053] When the push block 20 slides into the sliding cavity 11, until the outer end of the push block 20 is flush with the outer end of the stamping knife 14, the stamping knife 14 contacts the rubber sheet and starts to cut the rubber sheet; the pressing head continues to descend, and at the same time the push block 20 continues to slide into the sliding cavity 11 until the stamping knife 14 completely cuts out the circular rubber pad.
[0054] At this time, the cut circular rubber pad is completely squeezed in the sliding cavity 11 of the stamping head 10.
[0055] S4. The cutting die rises following the pressing head of the press, and the circular rubber pad is gradually pushed out of the sliding cavity 11 by the spring 40 and the push block 20.
[0056] S5. Manually remove the circular rubber pad pushed out from the sliding cavity 11, and move the rubber sheet and the plywood to the next cutting station.
[0057] Repeat the S3 - S5 steps of the cutting process until the cutting of the entire rubber sheet is completed.
[0058] It should be understood that the descending distance of the pressure head of the press can be manually set to avoid excessive descending distance, which may cause damage to the plywood under the rubber sheet during cutting.
[0059] It should be noted that when there is a description of "connected", "coupled" or "linked" between one element and another element, it may mean direct connection, coupling or linkage, but it should be understood that there may be intermediate elements between them; that is, it covers the positional relationship of both direct connection and indirect connection.
[0060] It should be noted that the use of similar words such as "a" or "an" does not necessarily indicate a limitation in quantity. Similar words such as "comprising" or "including" mean that the element or object appearing before this word covers the elements or objects listed after this word and their equivalents, without excluding other elements or objects.
[0061] It should be noted that terms indicating orientation or positional relationship such as "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships. They are for the convenience of describing the present invention, rather than the device or element must have a specific orientation, be constructed and operated in a specific orientation; when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.
[0062] The preferred embodiments for implementing the present invention have been described in detail above, but it should be understood that the functions of these embodiments are only for illustration, rather than limiting the scope, application or construction of the present invention in any way. The protection scope of the present invention is defined by the appended claims and their equivalent means. Those of ordinary skill in the art can make many changes to the foregoing embodiments under the teaching of the present invention, and these changes all fall within the protection scope of the present invention.
